Well, if he is spending a lot of time chatting and having fag breaks than he is not working. vegansrock has said he often doesn't turn up for one reason or another, so is not reliable.
If employing someone to do gardening work most people would want the job to be done properly, particularly as the rate per hour is that high. It's not a charity.
It is sad but he sounds as if he has got too comfortable and is taking them for a ride.
We probably pay about that rate for someone to come and cut lawns, do heavy pruning and other jobs as required but he doesn't stop and is excellent value for money.
